Class Method Details

.new(version: , credentials: , scopes: , client_config: , timeout: ) ⇒ Object

An intent represents a mapping between input from a user and an action to be taken by your application. When you pass user input to the DetectIntent (or StreamingDetectIntent) method, the Dialogflow API analyzes the input and searches for a matching intent. If no match is found, the Dialogflow API returns a fallback intent (+is_fallback+ = true).

You can provide additional information for the Dialogflow API to use to match user input to an intent by adding the following to your intent.

• Contexts - provide additional context for intent analysis. For example, if an intent is related to an object in your application that plays music, you can provide a context to determine when to match the intent if the user input is “turn it off”. You can include a context that matches the intent when there is previous user input of "play music", and not when there is previous user input of "turn on the light".

• Events - allow for matching an intent by using an event name instead of user input. Your application can provide an event name and related parameters to the Dialogflow API to match an intent. For example, when your application starts, you can send a welcome event with a user name parameter to the Dialogflow API to match an intent with a personalized welcome message for the user.

• Training phrases - provide examples of user input to train the Dialogflow API agent to better match intents.

For more information about intents, see the Dialogflow documentation.

Parameters:

• credentials (Google::Auth::Credentials, String, Hash, GRPC::Core::Channel, GRPC::Core::ChannelCredentials, Proc) —

  Provides the means for authenticating requests made by the client. This parameter can be many types. A Google::Auth::Credentials uses a the properties of its represented keyfile for authenticating requests made by this client. A String will be treated as the path to the keyfile to be used for the construction of credentials for this client. A Hash will be treated as the contents of a keyfile to be used for the construction of credentials for this client. A GRPC::Core::Channel will be used to make calls through. A GRPC::Core::ChannelCredentials for the setting up the RPC client. The channel credentials should already be composed with a GRPC::Core::CallCredentials object. A Proc will be used as an updater_proc for the Grpc channel. The proc transforms the metadata for requests, generally, to give OAuth credentials.

• scopes (Array<String>) —

  The OAuth scopes for this service. This parameter is ignored if an updater_proc is supplied.

• client_config (Hash) —

  A Hash for call options for each method. See Google::Gax#construct_settings for the structure of this data. Falls back to the default config if not specified or the specified config is missing data points.

• timeout (Numeric) —

  The default timeout, in seconds, for calls made through this client.

• metadata (Hash) —

  Default metadata to be sent with each request. This can be overridden on a per call basis.

• exception_transformer (Proc) —

  An optional proc that intercepts any exceptions raised during an API call to inject custom error handling.

Parameters:

• version (Symbol, String) —

  The major version of the service to be used. By default :v2 is used.
